COMPETING SERIES: There are no other series in this family. Metamora series are in a similar family and have a semiactive cation-exchange activity class. Metamora soils typically have rock fragments in the lower part of the series control section.

GEOGRAPHIC SETTING: Headlee soils are on flats, low knolls, and ridges on lake plains. Slope ranges from 0 to 1 percent. Headlee soils formed in 51 to 102 cm (20 to 40 inches) of loamy, water-sorted material and in the underlying lacustrine materials. Mean annual precipitation ranges from 762 to 1067 mm (30 to 42 inches). Mean annual temperature ranges from 8.9 to 11.7 degrees C (48 to 53 degrees F). Frost-free period is 130 to 180 days. Elevation is 183 to 396 meters (600 to 1,300 feet) above mean sea level.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Brady, Bronson, Gilford, Whiskerville, and Whitepost soils. The somewhat poorly drained Brady soils are on similar landforms but do not have lacustrine sediments in the lower part of the series control section. The moderately well drained Bronson and Whiskerville soils are on slightly higher positions on the landform. The poorly drained or very poorly drained Gilford and Whitepost soils are in depressions.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Somewhat poorly drained. Depth to the top of a perched seasonal high water table ranges from 15 to 46 cm (0.5 to 1.5 feet) between November and April in normal years. Potential for surface runoff is negligible to low. Saturated hydraulic conductivity is moderately high in the upper loamy material and moderately low or low in the lacustrine materials. Permeability is moderate in the upper loamy material and slow or very slow in the lacustrine materials.

USE AND VEGETATION: .Soils are mostly cultivated. Principal crops are corn, soybeans, wheat, and hay. Native vegetation is a mixture of deciduous forest and prairie grass.

DISTRIBUTION AND EXTENT: MLRA 111C in northern Indiana. The series is of small extent.

SERIES ESTABLISHED: Pulaski County, Indiana, 2001

REMARKS: Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon (mollic intergrade): from the surface to a depth of 23 cm (9 inches) (Ap horizon).
Argillic horizon: from a depth of 23 to 107 cm (9 to 42 inches) (Bt, 2Bt horizons).
Aquic conditions: redoximorphic features present in the zone between 23 and 165 cm (9 to 65 inches).

NASIS Data Mapunit ID 155021 represents the typical pedon in complex with Brady soils.

ADDITIONAL DATA: Lab characterization data is available for the typical pedon (S98IN-131-009) from the National Soil Survey Laboratory, Lincoln, NE. Transect data for the typical pedon (T97IN-131-187) is on file in MLRA project office, Plymouth, Indiana. Transect in a Headlee-Brady complex map unit shows 80 percent Headlee and similar soils, and 20 percent Strole soils.
